The Institute for the Study of War is a hawkish think tank closely allied with the U.S. military, which I mention because otherwise somebody might likely point it out. Nevertheless their assessment of the status of IS is credible and includes some helpful recent history. For some reason there hasn't been a lot of attention paid to this by U.S. media or politicians, but with the conquest of the last territory held by IS the Syrian Democratic Forces accepted the surrender of some 55,000 women and children, many or most of whom remain loyal to IS, and transferred them to a camp near the Iraq border. Nobody seems to have a good idea of what to do about this situation. ISW is reporting that meanwhile, IS is rebuilding its guerilla networks in Iraq and producing numerous bomb attacks. Iraqi forces continue a campaign against IS in northern Diyala province. So no, this is not over.
